A system and method of collision avoidance includes determining a position and an orientation, the position and the orientation being of a repositionable arm or of an instrument, the repositionable arm being configured to support the instrument; determining, based on the position and the orientation, a plurality of first virtual boundaries around the repositionable arm or the instrument; determining a second virtual boundary around an object; determining a first overlap force on the repositionable arm due to a first overlap between the second virtual boundary and a virtual boundary of the plurality of first virtual boundaries; determining a tip force on a distal end of the instrument based on the first overlap force; and applying the tip force as a first feedback force on the instrument or the repositionable arm.

In order to detect when a kinematic linkage (1) leaves workspaces (WS) and/or enters safe spaces (SS), using, little computing power, and therefore doing so more quickly, at least a part of the kinematic linkage (1) is modeled with a number of kinematic objects (K1, K2, K3, K4), and a monitoring space (S) is specified, The number of kinematic objects (K1, K2, K3, K4) is modeled in less than two dimensions D<2. For each modeled kinematic object (K1, K2, K3, K4), a geometric variable of a monitoring space (S) is modified by a distance (d1, d2, d3, d4). Each distance (d1, d2, d3, d4) is derived from at least one geometric parameter (P1, P2, P3) of the modeled kinematic object (K1, K2, K3, K4), The position of each of the number of kinematic objects (K1, K2, K3, K4) is checked in relation to the modified monitoring spaces (S1, S2, S3, S4).

A robot system is provided with a robot including a combination of mechanical units serving as multiple modules, a robot control device that controls the robot, and a memory provided in each of the mechanical units.

A robot control method includes defining a robot monitor model that covers at least a part of the robot and defining a monitor region parallel to a coordinate system for the robot. The monitor region is configured to monitor a range of motion of the robot. The method further includes transforming a position of a definition point that is an arbitrary point contained in the robot monitor model into a position of the definition point in a coordinate system different from the coordinate system for the robot (ST9), determining whether or not the robot monitor model is put into contact with a boundary surface of the monitor region by using the transformed position of the definition point (ST6), and stopping motion of the robot if the robot monitor model is put into contact with the boundary surface (ST8).
